Panduit FWTYL7575LNM049 12-Fiber OM5 49-Meter Trunk Cable Assembly
The Panduit FWTYL7575LNM049 is a 12-fiber OM5 multimode trunk cable assembly engineered for high-density data center environments where space efficiency and extended reach are critical. This 49-meter (160.76-foot) QuickNet™ assembly delivers four-wavelength short-wavelength division multiplexing (SWDM) capability, enabling 100-meter reaches at 40G and 100G speeds over a single duplex connection. The small-diameter trunk design reduces pathway fill by 30 to 40 percent compared to traditional 50µm multimode assemblies, directly addressing the congestion challenges integrators face in modern hyperscale and colocation facilities. Lime-colored LSZH jacketing provides both visual circuit identification and low-smoke-zero-halogen fire safety compliance for enclosed equipment rooms and plenum-adjacent pathways.
Key Features
- OM5 wideband multimode fiber supports four-wavelength SWDM transmission for 40/100G applications over 100-meter links using a single duplex interface
- 12-fiber count provides six duplex channels in a single trunk assembly, reducing connector density at patch panels and switch faceplates by 50% versus individual duplex jumpers
- Small-diameter trunk construction reduces conduit and cable tray fill by 30-40%, enabling higher fiber density in constrained pathways without exceeding NEC fill ratios
- 49-meter factory-terminated length bridges typical intra-building data center spans including cross-connects between main distribution areas (MDA) and intermediate distribution areas (IDA)
- Lime LSZH jacket meets IEC 60332-3-24 Category C flame propagation and IEC 61034-2 low-smoke requirements for international compliance and equipment room safety
- Factory-terminated with polarized connectors and full insertion-loss testing eliminates field termination labor and ensures day-one link performance
- QuickNet™ platform integrates with Panduit's labeling, cable management, and copper infrastructure for unified pathway design
- 50µm core diameter maintains backward compatibility with existing OM3 and OM4 multimode infrastructure while providing 4x spectral efficiency via SWDM
- Pre-tested assemblies include serialized test reports documenting insertion loss per fiber pair, reducing commissioning time and simplifying acceptance testing
- RoHS-compliant construction meets European and California material restriction requirements for enterprise procurement policies
OM5 wideband multimode fiber represents a generational shift in multimode infrastructure economics. Unlike OM3 (2000 MHz·km at 850nm) and OM4 (4700 MHz·km at 850nm) fibers optimized for single-wavelength transmission, OM5 fiber delivers 4700 MHz·km bandwidth across four distinct wavelengths in the 850-950nm window—850nm, 880nm, 910nm, and 940nm per TIA-492-AAAD specifications. This four-lane capability allows SWDM-enabled transceivers to transmit 100GBASE-SR4 over a single duplex LC connection rather than requiring eight fibers in a parallel optics configuration. For integrators managing spine-leaf architectures or storage-area-network fabrics, this means a 12-fiber trunk like the FWTYL7575LNM049 can support six independent 100G links instead of requiring 48 fibers for the same port count. The reach advantage is equally significant: OM5's wideband design maintains 100-meter link budgets at 40G and 100G speeds, compared to the 70-meter OM3 limit, providing the margin needed to accommodate structured cabling with cross-connects and consolidation points. The 50µm core diameter ensures OM5 fiber remains compatible with existing OM3/OM4 infrastructure—you can mix OM5 trunks with legacy OM4 backbone links and existing 850nm transceivers without requiring forklift upgrades. This backward compatibility protects installed infrastructure investments while future-proofing pathways for SWDM migration as transceiver costs decline.
The small-diameter trunk construction addresses the single most common constraint in retrofit data center upgrades: conduit and cable tray fill capacity. Traditional 12-fiber distribution-style cables with 900µm tight-buffered fibers yield outside diameters near 10mm; breakout-style assemblies with individual 3mm zipcore legs consume even more volume when bundled. Panduit's QuickNet small-diameter trunk uses sub-2mm individual fiber elements with a ruggedized common jacket, resulting in an overall cable diameter 40% smaller than conventional 12-fiber constructions. For a typical 4-inch conduit run between a main equipment room and an intermediate distribution frame, NEC Article 770 limits multimode fiber fill to 1.963 square inches (40% of conduit cross-section). A conventional 10mm 12-fiber cable consumes 78.5 sq mm per trunk; the FWTYL7575LNM049's smaller diameter drops fill to roughly 47 sq mm per trunk, increasing conduit capacity from 16 trunks to 26 trunks—a 62% capacity gain without any civil work. This density advantage cascades to cable trays, vertical pathway risers, and under-floor grids where space contention between fiber, copper, and power distribution limits growth. The 49-meter factory-terminated length suits the majority of horizontal and vertical distribution runs in enterprise data centers: equipment room to adjacent IDF (15-30m), floor-to-floor riser (3-4.5m per story × 10 floors = 30-45m), or MDA to perimeter equipment row in a 10,000-square-foot facility (diagonal span ~43m). Factory termination eliminates the field labor, consumables cost, and quality variability of on-site fusion splicing or mechanical termination, while pre-test certification provides serialized insertion-loss documentation that satisfies TIA-568 Tier 1 or Tier 2 acceptance testing requirements without deploying an OTDR to the jobsite.
LSZH jacketing is now the de facto standard for enclosed data center spaces and any installation subject to international building codes. Low-smoke-zero-halogen compounds produce 20-40% of the smoke volume of PVC jackets during combustion and emit no hydrochloric acid or other halogenated gases that accelerate corrosion of active electronics and create respiratory hazards during evacuation. The FWTYL7575LNM049's lime jacket meets IEC 60332-3-24 Category C (vertical flame propagation on bundled cables) and IEC 61034-2 (light transmittance >60% during combustion), ensuring compliance with European CPR Euroclass standards, Canadian ROHS, and Australian AS/NZS 3080. The lime color follows TIA-598-D coding for OM5 fiber, providing instant visual differentiation from aqua OM3 and erika violet OM4 trunks during adds/moves/changes—critical when a single equipment rack may house a mix of legacy 10G multimode, current 25G single-mode, and future 100G OM5 links. Trunk assemblies with pre-labeled connectors and strain-relief boots further reduce installation errors; the QuickNet platform integrates with Panduit's NetRunner cable managers, PatchRunner vertical organizers, and angled patch panels to maintain the 38mm (1.5-inch) bend radius required by TIA-568-C.3 for 50µm multimode fiber, preventing the macrobend-induced loss spikes that plague hastily dressed fiber installations.
